"Univocal, Equivocal, & Analogical Terms"

From

Aristotle's "Categories" 1:


"Things are said to be named 'aequivocally' when, though they have a common name, the definition corresponding with the name differs for each."

"Thus, a real man and a figure in a picture can both lay claim to the name 'animal'; yet these are equivocally so named, for, though they have a common name, the definition corresponding with the name differs for each."

"For should any one define in what sense each is an animal, his definition in the one case will be appropriate to that case only."

---- Ditto, Kilgariff was irritated that the Longman Dict. of English, for which he worked, had:

horse: an animal; representation of a horse.

---- "I don't believe in word senses".

---

"On the other hand, things are said to be named 'univocally' which have both the name and the definition answering to the name in common."

"A man and an ox are both 'animal', and these are univocally so named, inasmuch as not only the name, but also the definition, is the same in both cases."

"For if a man should state in what sense each is an animal, the statement in the one case would be identical with that in the other."



From Ralph McInerny's Aquinas & Analogy, p. 96:


"Things are to be named ANALOGOUSLY when, though they do have a name [or predicate. Speranza] in common, the definitions corresponding with the name are partly the same and partly different, with one of those definitions being prior to the others."

"For example, 'healthy' as said of urine signifies a sign of the health of the animal, but said of medicine it signifies the CAUSE of the same health" [St. Thomas, Summa Theologiae I.15.5c]."

Similarly for Grice:

Those spots mean measles.
What they mean is the thing causing measles.

---






"The pig on the front and the pig in the back are given the name "pig" univocally (same name, same meaning)."

"The pen in which the pigs are eating and the pen used for writing are given the name "pen" equivocally (same name, different meaning)."

ANALOGY: ANALOGOUS.

"The pigs may be said to be "healthy" pigs, and the food they are eating may be said to be "healthy" food."

"Now, the pigs and the food are both "healthy" analogically, i.e., in different, though related, senses of the word."


Actually, the same 'sense', Grice would say. There is a pragmatic ambiguity, as Grice calls it. The logical form should deliver this.

"The pigs are healthy in the strict sense of having proper biological functions, but the food is only healthy in reference to the health of the pigs."

"The food is healthy in an analogical sense because it causes the health in the pigs."

"The food does not have the proper biological functions that warrant the pigs' being called "healthy" in the strict sense."

And so on.

So perhaps,

By uttering 'x is healthy' U means the CAUSE, and 'implicates' something different?
